BAKING-PAN.

Specification of Letters Patent.

Patented Jan. 14, 1919.

Application filed April 10, 1917. Serial No. 160,923.

To all whom it may concern:

Be it known that I, HARRY J. HAIGH, a citizen of the United States, anda resident of Stapleton, Staten Island, borough and county of Richmond,and State of New York, have invented certain new and useful Improvementsin Baking-FansQof which the following is a specification.

This. invention relates to that. class of baking pans, largely employedin bakeries, in which a plurality of individual pans are connectedtogether to form a multiple bak- 111g pan.

The principal object of the present invention is to provide means fordetachably connecting the pans together, whereby a damaged pan may beremoved from the set and anew plansubstituted, or the relative positionsof the pans of a set changed to present a different pan or pan surfaceat the point or points of greatest wear. Another object of the inventionis to provide a rigid holding frame to which the individual pans may berigidly secured; and held against relative movement, without theemployment of rivets or other fastening devices exposed at the innersurface of the pans.

A further object'of the invention is the provision of a connecting frameand means connected with the pans adapted to be rigidly interlockedwiththe frame to hold the pans to the frame and in proper positionrelatively to each other. Another object of the invention is to providea connecting frame adapted to be expanded to facilitate the removal andinsertion of the pans.

Another object of vide individual pans having permanently securedthereto means adapted to be detachably and interchangeably connectedwith a standard type of connecting frame for rigidly securinga-plurality of pans together. In the accompanying drawings, is aperspective view showing one form of multiple pan embodying theinvention;

Referring to the drawings by numerals, l designatesthe individual pans which ma be constructed in any suitable manner.rectangular wire reinforcing frame or memher 2 extends around the upperedge of each pan and is preferably held thereto by bending or rollingthe upper edges of the side and end walls of the pan outwardly anddownwardly around the frame 2, as shown.

locking lug or member 3 is rigidly secured to each end wall of each ofthe ans 1 in any suitable manner. I prefer to fbrm the lugs 3 withelongated upper portions 4 and to bend the portion 4 outwardly anddownwardly around the end portions of the wire reinforcing frames 2before the end form. of divided end.

walls of the pans 1 are bentaround said end portions, as shown moreclearly in Figs.

3 and 4. The portions 4 of the lugs 3 are preferably of substantiallythe same length J The pans 1 are rigidly held together, preferably inspaced relation, as shown, within a rectangular connecting framecomprising side bars 6 and divided and extensible end bars. The end barsare riveted to inwardly bent ends 7 of the side bars 6, as shown vat 8,but it will be obvious that the end bars may be formed integrally withthe side bars if desired. The end bars of the frame may be dispensedwith, if desired, and the pans held together, solely by the side bars 6.

The extensible end bars of the connecting frame are preferably formed ofa member or bar 9 having a bifurcated inner end, as shown at 10, and amember or bar 11 having a reduced extension 12 adapted to slidelongitudinally within the bifurcated end 10 of the bar 9, as shown inFigs. 5 to 8. The inner end of the extension 12 on bar 11 is hinged at13 to a plate 14, and the inner ends of the arms or extensions 10 on bar9 are hinged at 15 to a plate 16. The plates 1 1 and 16 are hingedtogether at their inner ends as shown at 17. The extensions 10 and 12are preferably bent or depressed inwardly as shown at 18 and 19. Whenthe hinged plates 14: and 16 are swung inwardly toward the sidewalls ofthe end pans, as shown in Figs. 2 and 7 it will be seen that the bars 9and 11 will be pulled'toward each other, the extensionv 12 movingbetween the extensions 10 until the depressions 18 and 19 are inalinement, whereupon the hinge pintle 17 connecting the plates 14 and 16may be forced inwardly past center, as shown inFig. 7, into theregistering depressions 18 and 19. The bars 9 and 11 are thus locked incontracted position and the side bars 6 are moved inwardly against theend walls of the pans and held thereagainst with the tubular ends 5 oflugs 3 projecting through apertures 20 in the side bars. At polnts abovethe apertures 20 the side bars 6 are preferably pressed outwardly asshown at 21, to form depressions or seats for the depending portions 3of the locking lugs. By this arrangement the side bars may lie flushwith the end walls of the pans.

Any suitable means may be provided for positively and detachably holdingthe side bars 6 against the end walls of the pan, if desired, to preventseparation of the pans in case hinge pintle 17 should be accidentallyside bars 6 are preferably formed with projections 2A for holding thepins in looking position, the heads 25 of the pins being adapted 24 andengage behind the same when the pins are inserted through the'eyes 23and the tubular extensions 5 on the lugs 3.

In the embodiment of the invention shown in Figs. 10 to 15, the pans 1are provided with wire reinforcing frames-2 preferably secured theretoin the manner heretofore described, and the pans are held within anexpansible connecting frame comprising side bars 6 and expansible endbars formed of members 9 and 11 connected together by hinged plates 14and 16 in the same manner as the members 9 and 11 shown in Figs. 5 to 8,except that the depressions 18 and 19 in the extensions 10 and 12 arenot shown, it being understood that said depressions may be employed ordispensed with in either embodiment of the invention. As shown in Figs.10, 11 and 14, the end bars are formed with bent end portions riveted at26 to the ends of the side bars 6, but the side and end bars may beconnected as shown in Figs. 1 and 2, or in tegrally formed, ifpreferred.

A fastening device is permanently held to the end walls of each pan andcomprises a portion 27 bent outwardly and downwardly around the endportions of the reinforcing wire frames 2, as shown in Figs. 12 and 15,and formed with a pair of spaced depending lugs 28 having outwardlyprojecting portions 29 formed with enlarged heads 30. The side bars 6are formed with two apertures opposite the end of each pan havingenlarged portions 31 through which the heads 30 of the lugs 28 areadapted to pass and reduced portions 32 adapted to receive theprojecting portions 29 of the lugs 28 when the pans are moved laterallyin the frame to lock the pans to the frame.

To prevent shifting and accidental detachment of the pans, bars 33 arepivoted intermediate their ends onthe side bars 6. It will be seen thatwhen the bars 33 are swung to horizontal position, the opposite ends ofthe bars engage between heads 30 on lugs on adjacent pans and preventlateral movement of the pans. It will be observed that the arrangementof the large and reduced portions of the apertures opposite the end panat the left in Figs. 10 and 11, is the reverse of that of the otherapertures in order that when the end pan at the left is shiftedlaterally to locked position it will be moved closely against theadjacent end bar of the connecting frame. The end bars, or-theexpansible joints connecting the divided end bars, desired, and the sidebars 6 only.

From the foregoing it will be seen that simple means has been providedfor rigidly connecting together a plurality of baking pans in such amanner that any pan of a set may be removed and a new pan substitutedtherefor, or the relative positions of the pans altered. By thisarrangement the period of usefulness of a multiple baking pan may begreatly prolonged by placing worn pans at a point where they will besubjected to less wear and strain, and by substituting new pans for wornor damaged pans.
